UNITED STATE PATENT @FFlGEO JOHN B. HEVERLING, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HENRY ZEGEN- HINE, OF SAME PLACE.

MACHINE FOR SHAPING BARREL-STAVES.

SPECIFICATION forming part of Letters Patent No. 283,886, dated August 28, 1883.

Application filed April 14, 1883. (No model.)

To aZZ whom it may concern Be it known that I, JOHN B. HEVERLING,

A of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Machines for Shaping Barrel- Staves, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings, forming part of this specification.

This machine is for the purpose of forming the outer and inner surfaces of staves, more especially of the class used for beer-barrels.

The scope of my improvement is set forth in the claims. t

Figure 1 is a top view of the machine. Fig. 2 is a rear elevation. Fig. 3 is an end elevation. Fig. 4 is a cross-section at 4 4, Fig. 1. Fig. 5 is a perspective view of one of the dogs. Fig. 6 is a detail vertical section at 6 6, Fig. 8. Fig. 7 is a horizontal section at 7 7, Fig. 4.

Fig. 8 is an enlarged detail view of part of a revolving head with a stave in cross-section. Fig. 9 is a vertical section at 9 9, Fig. 7. Fig. 10 is an enlarged longitudinal section of a stave with a top view of parts of the cutters,

showing outline of the knife-edges. A is the frame of the machine. B is a drive-pulley, turning free on the shaft C, supported in suitable bearings, l), on the frame. Upon the hub of pulley B are ratchetteeth 13 engaging similar teeth E on a clutch collar, E, feather-keyed to the shaft 0 so as to slide laterally thereon and to turn positively therewith. The clutch-collar is moved upon 3 5 the shaft by the usual lever and yoke, F, engaging a circumferential groove of the collar, and acting to engage the shaft and clutch with the pulley B or to disengage them.

G are pinions upon the shaft 0, that engage the peripheral cogs H upon the heads H. The heads H have circumferential bearing in cases I, that are secured to the frame A and secured together by longitudinal bars J J. The ends of the cases I extend inward toward the center, thus incasing the outer sides of the heads H, and the heads are held in the cases on the in ner side by lips K. The distance between the At the inner side of one head and near the periphery are a number of holding-teeth, L, by which one end of the stave M is held while the other end of the stave is held by a sliding dog, N, having suitable holding-teeth, N. The dog has a lip, N, by which it is held in and drawn out at the proper time. 0 is a projection of the inner side of the head, which bears against the rear edge of the stave and carries it forward between the cutters.

P is a cradle, of whichthere is one at each end of the machine, and within or upon which the stave is laid, the cradles acting as guides to insure the proper position of the stave. As the dogs come in line with the stavethe latter is taken up by the projections O, and at this time the holder N receives a blow of a mallet, engaging the ends of the staves on teeth N and L. As theheads turn forward, the lip N passes beneath the flange Q, and the holder is held firmly in the stave. After the stave has passed between the cutters the lip comes in contact with an inclined cam or bar, It, and as the headsturn forward the pressure of the cam against the inside of the lip N draws the holder out and disengages the stave. If, how 7 5 ever, the stave shall not have been fully disengaged from the teeth, it is disengaged therefrom by coming in contact with the under side of the cradles P and knocked loose from the head. The cutters are revolved at a rapid speed and in opposite directions, so as to cut in an opposite direction to that in which the stave is fedfor instance, as shown in the drawings, the staves are fed downward, consequently the cutters are made to cut upward. The distance of the staves asunder diametrically to the head is nearly the same as the diameter of the cask, and the knives or cutters, beside being formed to give the propereontour to the surface longitudinally, are placed the requisite distance asunder to leave the stave of the proper thickness, so that both in thickness and in the shape of the outer and inner surfaces the stave is perfectly formed.

' The inner cutter is shown at S, carrying knives S, extending the whole length of the stave, and so formed as to impart to it the shape desired. In like mannerthe outer out ter-head, T, has knives T formed to shape the outer side of the stave. The stave passes downward between the cutters, and the knives cut upward, as indicated by arrows in Fig. 4,

I claim v 1. In a stave-dressing machine, the combination of cases I, heads H, having circumferential bearing in the cases, and provided with peripheral cogs H and a common drive-shaft having pinions for rotating the heads in unison, as set forth.

2. In a stave-dressing machine, the combination of cases I, heads H, having circumferenti a1 bearing therein, and formed with peripheral cogs, suitable holding dogs projecting inwardly from the heads, and a common driveshaft having pinions to mesh'with the periph eral cogs of the head and turnthem in unison, as set forth.

3. In a stave-dressing machine, the combination of the heads H H, one head provided with fixed teeth and the other head with slidin g dogs having suitable teeth, and means for turning the heads in unison, as set forth.

4. In a stave-dressing machine, the combination of ahead having holding-teeth L, a head having dogs N, with holding-teeth N and lips N the flange Q, for pressing the dogs inward,

and means for turning the heads in unison, as

set forth.

5'. In a stave-dressing machine, the c'ombination of a head having fixed holding-teeth, a head having dogs N, with holding-teeth N and lips N the cam-bar R, for withdrawing the dogs by engaging with their lips, and means for turning the heads in unison, as set forth.

6. In a stave-dressing machine, the combination of the rotary heads H and revolving cutters 'I and S, having knives the full length of the staves and formed to give the finished shape to the staves on their upper, inner, and outer surfaces, as set forth.

7. In a stave-dressing machine, the combination of the rotary heads having holdingteeth and projections, the cutters, and the eradles, the projections adapted to lift the staves from the cradles and to force them between the cutters, as set forth.

8. In a stave-dressing machine, the combination of the rotary heads H, having means for holding and carrying staves, the cutters T and S, and the cradles P, for insuring the proper position of the staves, as set forth.
